10 people who build at the same rate can frame a house in 6 days. What fractional part of a house can 4 people frame a house in

Alina [70]

10 people who build at the same rate can frame a house in 6 days. That means it will take one person $10\times6=60$ days to finish the house.

Which means that it will take 4 people $\frac{60}{4}=15$ days to finish the house.

So, the fractional part of the house 4 people can frame in 3 days will be $\frac{3}{15}=\frac{1}{5}$

Thus, Option D is the correct answer.

First, need to find 15% of 47.28.

Madison is making party flavors she wants to make enough flavors so each guest gets the same number of flavors she knows there w

bazaltina [42]

Answer:

Step-by-step explanation:

To find the least number of party favors, we have to consider the number of guests.

In this case, there are two possibilities—6 or 8.

For 6: 6, 12, 18, 24 (Add 6 to each number)

For 8: 8, 16, 24 (Add 8 to each number)

Now in both series, the least number (that is in common) is 24. Hence, Madison should make at least 24 party favors.
